<p>
The 7075 aluminum price per kg is higher than alu sheets of other series. 7075
aluminum sheet is a cold-treated forging alloy with high strength and high hardness, far better than mild steel. <strong>Aluminum 7075 price per kg</strong> is high first because it’s one of the most powerful alloys in the industry, with common corrosion resistance, good mechanical properties and anode reaction. Fine grain makes the deep drilling performance better, the tool wear resistance is enhanced, the thread rolling is more different from the weight, and the preferred metal material with higher hardness requirements and higher hardness requirements. Zinc is the main alloying element in aluminum 7075. Adding magnesium to an alloy containing 3%-7.5% zinc can form MgZn2 with remarkable strengthening effect, which makes the heat treatment effect of the alloy far better than the aluminum-zinc binary alloy. Increasing the zinc and magnesium content in the alloy will further increase the tensile strength, but its ability to resist stress corrosion and flaking corrosion will decrease. Of course, this increases cost of 7075 aluminum per kg.<br></p>
<p>
Aluminum 7075 price per kg is high for the following reasons.</p>
<p>
High Production cost</p>
<p>
7075 aluminum is a copper-zinc-
aluminum alloy. The ingot is difficult and the probability of failure is high. The cost of production by repeated ingots is much higher than that of ingots such as 5052.</p>
<p>
High Technical Requirement</p>
<p>
7075
aluminum plate, especially <strong>7075-T651
aluminum plate</strong>, has a high hardness and cannot be rolled by ordinary hot rolling mills. This requires advanced technological backup and large production scale.</p>
<p>
Demand and Supply</p>
<p>
Because of the production cost and technical reasons, the supply of 7075
aluminum plates is small, and the cost of 7075 aluminum per kg naturally rises. In the final analysis, the aluminum 7075 price per kg is 20 yuan/kg higher than the <strong>5083
aluminium sheet price per kg</strong>.</p>
